If Cisco could ship enough units when asked, I'd say their next couple 
of quarters are in the bag... but since they have such huge lead 
times..... well, I am guessing a lot of people will start considering

Transit providers would do well to have a distribute-list or similar 
configured to offer these guys when they call rather than trying to 
engineer something on an ICB basis.
